Number 4™ Clarifying Shampoo

At the end of a long day we could all use a fresh start——and the same goes for our hair. When product buildup and styling stress leave strands feeling and looking dull, this clarifying shampoo, subtly scented with white freesia, golden amber, and warm musk, gently cleanses without stripping moisture or color. Black currant and soy restore vibrancy, acai berry and vitamin C deliver youth-boosting antioxidants, oolong tea and Irish moss defend against environmental damage, and lemongrass and oatmeal gently cleanse and purify. This shampoo is also vegan-friendly and free from sulfate/sodium chloride and parabens.

I was a little taken aback by the texture of this shampoo, but was pleasantly surprised at how clean my hair felt!

Nice Shampoo
Sampled

I liked the way my hair felt after I used this shampoo, but because my hair is normally dry and I don't use styling products all the time, I'd probably only use it a couple of times a month.

At first I was not a fan of the smell of this product, but after multiple uses i actually think that the smell is very subtle and clean. I'm not a fan of the consistancy but I love the way that it makes my hair feel!

Good shampoo

The smell was nice and it made my hair feel nice after but I felt like it didn't lather much and I had to use twice as much product. Also my hair got greasier faster

Hair perfection

I am obsessed with this clarifyer. It is like none other that I've tried. Usually they are drying but this one leaves my hair soft and smooth. I also have to use way less conditioner now. I think I've found my shampoo soulmate.

That texture tho~
Sampled

I was so surprised when I put this shampoo in my hair, it's so much thicker and almost like a paste, but as soon as I hit it with some water it lathered quite nicely. I really enjoyed using it followed by the mask of this brand. My hair was super soft after it dried.

Great concentrated shampoo
Sampled

My hair is so soft and shiny after using this, like with the other No. 4 products I have tried. Scent is fabulous. I use minimal product, so I may not be the best to evaluate how well it "clarifies," but my hair looked great! And this is concentrated. That may help me get over the price - ouch.

No 4 Clarifying Shampoo

I liked the smell, but ended up having to use a lot of product to get my hair completely clean. I might repurchase this; I like having a weekly deep-hair cleaning shampoo and this one didn't leave my hair feeling stripped or gross.

This product smelled great and left my hair feeling clean. It didn't leave me feeling dry which I really liked.
